IVIITER AND TRY-SQUARE.

Application led May 29, 1916.

To all whom it may concern:

Be it known that I, CHRISTIAN BoDMnR, a citizen of the United States ofAmerica, residing at New Britain, Connecticut, have invented a new anduseful Miter and rIry- Square, of which the following is aspecification.

My present invention is a combination miter and try-square and theobjects of the invention are to provide a simple and practical form oftool which can be readily used at will to serve the functions of atrysquare or miter.

A special object is to provide a tool of the above mentioned characterhaving a work ing blade which may be adjusted as to length to suitdifferent requirements.

In the accomplishment of these objects and others as will later appear,I construct the tool with a stock having a ninety degree or right anglestraight edge at one side and a forty-five or miter straight edge on theopposite side thereof and I provide a working blade which is slidablyengaged in the tool stock and is also pivotally secured so that it maybe swung from one side of the tool stock over to the opposite side ofthetool stock.

A special feature of the invention is the provision of the tool stockwith an opening therethrough located between the straight edges at theopposite sides thereof and providing clearance for the end of the bladein swinging over from one side to the opposite side of the tool head.

Another feature is the provision of bearing seats at the opposite endsof said opening providing supports for the blade in the planes of therespective straight edges.

A further feature is a special form of slotted bolt for holding theblade in adjusted relation in the head, carrying a pin working in alongitudinal slot in the blade.

In the accompanying drawing I have illustrated the invention embodied inthe practical and preferred form but it will be understood that changesand modifications may be made without departing from the true spirit andscope of the invention.

In said drawing, Figure 1 is a face view of the tool partly broken toshow the bearing seats for the blade and indicating, in dotted lines,the action of swinging the blade from one side over to the opposite sideof the head. Fig. 2 is a sectional view taken Speciication of LettersPatent.

substantially on the plane of the line 2-2 of Fig. 1. Fig. 3 is a viewof the invention as embodied in a. square.

The tool stock 7 is made with a ninety degree face or straight edge 8 atone side thereof and a forty-five degree face or straight edge 9 at theopposite side thereof, the two straight edges converging to a headportion in which the marking blade 10 is secured. This blade is providedwith a longitudinally extending slot 11 therein having closed ends andextending usually about half the length of the blade.

The marking blade seats in a slot 12 formed in the head and extendingthrough from the straight edge at one side to the straight edge on theopposite side, bearing seats 13 and 14 for the blade being provided atthe opposite ends of the slots in the planes of the respective straightedges.

At a point between the bearing seats the tool stock is recessed orformed with an opening as indicated at 15, leaving the two bearing seatsseparated from each other so that the blade rests on two separate pointsof support and providing also clearance for the end of the blade whenturning the blade over from one side to the opposite side, as will beclear in the dotted positions of the blade shown in Fig. 1.

The blade is adjustably held to its seat by a clamping bolt or post 1Gseated in a bore 17 in the tool stock and slotted as indicated at 18 toprovide arms 19 disposed at opposite sides of and receiving between themthe thickness of the blade. A pivot pin 20 connecting these arms worksin the slot 11 in the blade and the exposed end of the bolt is usuallythreaded to receive a clamp nut 21.

The use of the device will be clear from the foregoing it being apparentthat upon loosening the thumb nut 2O the blade may be easily slid overand secured at any desired length and may further when desired be swungover from a position cooperating with the one straight edge intoposition at the opposite side of the head coperating with the otherstraight edge which makes it possible to adapt the tool to manydifferent requirements. The recess or opening 15 left between thebearing seats is of especial advantage in that it prevents the cornersof the blade being injured in the movement of swinging the blade fromone side the blade is bearing on the opposite seat -whichneeds notruingf the ,movement of this cutting blade thenserving ,to .quicklyAreducevthe high bearing seat `to its proper height. It will be evidentthat the features .of the invention canas well .be incorporated in theusual type of try-square as indicated :in

Fig. 3 where except for the: tool stock being l,designated 7 ,andthestraight edges being ldesignated 8 and 9 the reference characters arethe same.

What I clainris:

l., A combined miter and try square coniprising a tool stock havingconvergently, arranged mitering and :squaringedges and a bladepivotallysecured in the yhead `of the tool stock between said edges and adaptedto be swung fromcoperating relation with one of said yedges overV tothev opposite side of the head into coperatmg relation with vthe otheredge with a seat on each side of the pivotalmountingfor said blade,vsaid yseatsibein-g positioned to simultaneously engage one side edgelof said/blade .to definitely establish the angular position of saidblade and stock.

2.?In a tool of the character set forth, a tool stock havingstraightedges at opposite sides thereof and a slot extending' therethrough fromonestraightedge to the .other straightedge, a blade seated insaidslotand formed itself with a longitudinal slot and a clamping bolt `mountedin the toolk stock and ,provided` with a pivot pin working in the slotin the blade to thereby permit ,of .thefblade beingswung on said pivotfrom cooperating relation with thel straight edge ony one side ofthetool ,over into coperatingrelation with the other straight edge onthe.-.oppo

site side of the tool with a seat on each side of the pivotal mountingfor said blade, said seats being positioned vto 'simultaneously engageonefside edge ofA saidblade to deflnitely establish the angular positionof said blade and stock.

3. In a tool of the character set forth, a tool 4stock having straightedges atoppo- Y site sidesthereof, and a slot extending therethroughfrom one straight edge to the other straight edge, a.-blade -seated -inysaid slot andr .formedy itself vwith .ai ylongitudinal slot, a clampingbolt mounted inithe, toolstock and provided with afpivot7 pin working in.the slot in.k the blade toz thereby permit yof the ybladebeingswung-.on said pivot from ccperating relation with thestraight-edge onv one side of the toolover ,into coperating relationwith the other straightedge on,- thejopposite side of theitool,,saidetool stock `having gan. openingf extending therethrough ,locatedbetween the straight; edges to provide clearance for .the-.end 4of theblade inswinging, over from oneside to the Aopposite. side .of the 7toolstock and provided withffbearing -seatsfor theblade vat the oppositeends ofsaid opening.`
